I have the red and the blue sets, and they are awesome. This yellow set is different. They’re about half the weight and density of the others, and they are much more spongy and squishy feeling. They’re still good quality, and look great. However, they’re the same price as the other sets, but feel like a completely different product. This doesn’t compromise the handling. They’re just balls, and they’ll do the job. I feel slightly ripped off for paying the same amount and receiving something made out of lesser quality material. All that being said, I’ll still use them. They work.
